As of 30-Jul, Navin Fluorine International Ltd is experiencing a price increase, currently at 5,194.45, reflecting a rise of 46.7 or 0.91%. The stock has recently hit a new 52-week and all-time high of Rs. 5244, and it has been gaining for the last three days, with a total return of 3.39% during this period. The stock is trading above its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, indicating strong momentum. Despite a decline in investor participation, as evidenced by a 25.71% drop in delivery volume, the company has demonstrated high management efficiency with a return on capital employed (ROCE) of 16.05% and a low debt-to-EBITDA ratio of 1.08 times. The recent financial results have been very positive, showcasing a significant net profit growth of 128.85% and strong operating profit margins.
In the broader market context, Navin Fluorine has outperformed the benchmark, with a one-week return of +2.86% compared to the Sensex's -1.50%, and a year-to-date return of +59.99% against the Sensex's +4.28%. This performance is notable given that the broader market has faced negative returns over the past year. While the stock has shown strong short-term gains, concerns about its long-term growth persist, with an annual operating profit growth rate of only 12.84% over the last five years and a high PEG ratio of 4.2, suggesting that the stock may be overvalued relative to its earnings growth.
